PURPOSE:To unnecessitate the correction of the form of product portions after mold clamping by a method wherein guide pin mounting holes are eccentrically bored in bushings on either one of a stationary mold and a movable mold and pin insertedly fitting holes are bored in bushings on the remaining mold. CONSTITUTION:The positional shiftings of bushing holes 51 and 61 are checked with reference to the forms of product portions 11 and 12 the state that a stationary mold 1 an a movable mold 2 are mounted on a setting press. Bushings 41 and 71 are mounted to a guide pin 15 according to the checked positional shift and the positions of the bushings 41 and 71 with respect to the guide pin 15 are fixed. Similarly, the positions of bushings 42 and 72 with respect to a guide pin 16, the positions of bushings 43 and 73 with respect to a guide pin 17 and the positions of bushings 44 and 74 with respect to a guide pin 18 are respectively determined and fixed. When the guide pins are insertedly fitted to the bushing holes of the stationary mold 1 and of the movable mold 2 in the state that no position of the bushing with respect to the guide pin is changed, no correction of the form of the product portions is necessary after the stationary mold and the movable mold are clamped together with each other. |
